Magnum Venus Plastech DP-1000 (EPO3) - Manual (Page 23)

Attach red line-air hose from manifold of unit (located on the pump pivot support bracket) to quick-
disconnect.
(Figure 24. Extend Charging Pump Handle)
(Figure 25. Attach Charging Hose)
Be sure recirculation valves (located on the INLET PANEL) are open so fluid can exit accumulator
during charging.
The gauge on the charging pump should read line pressure.
Operate charging pump by placing handle against your chest and pressing pump against the handle.
Charge accumulator to approximately 100 psi less pressure than the fluid pressure reached when
setting up the proper spray pattern.
Wait until fluid is out of the recirculation hose before final stroke of the charging pump.
The gauge needle will bounce slightly during pumping and you should only refer to the pressure
reading reached at the peak of the bounce during the retraction stroke of the charging pump. (Air
escaping from the recirculation hose indicates gelled material at the accumulator ball seat).
Remove air quick-disconnect from charging pump and then remove hose fitting from accumulator
charging valve.
Stroke pump several times to remove fumes which could contaminate the other accumulator.
Repeat entire procedure on opposite accumulator at the same charging pressure. Replace
accumulator charging valve caps.
Test spray, or pour, again (see Section 5) and watch for pulsations. Check for air leaks.
